1、傳統(tǒng)的SDH傳輸網(wǎng)絡(luò)面臨許多問(wèn)題和挑戰(zhàn)，如業(yè)務(wù)擴(kuò)展性差，不能及時(shí)滿足用戶多業(yè)務(wù)需求?；贛STP的SDH傳輸網(wǎng)絡(luò)通過(guò)各技術(shù)的融合來(lái)達(dá)到對(duì)數(shù)據(jù)、話音、圖像多業(yè)務(wù)支持的目的，打破新業(yè)務(wù)發(fā)展的瓶頸。木研究屬于網(wǎng)絡(luò)應(yīng)用研宄，旨在探討基于MSTP技術(shù)的SDH傳輸網(wǎng)絡(luò)的關(guān)鍵技術(shù)，通過(guò)對(duì)目前較為先進(jìn)的SDH、MSTP技術(shù)發(fā)展現(xiàn)狀的歸納總結(jié)，以及傳輸網(wǎng)技術(shù)的深入研究，提出了基于MSTP的SDH傳輸網(wǎng)絡(luò)在企業(yè)專網(wǎng)的實(shí)現(xiàn)方案，解決電力通信多種業(yè)務(wù)統(tǒng)一傳輸?shù)膯?wèn)題。木文的主要工作如下：首先，木文對(duì)電力通信網(wǎng)絡(luò)的現(xiàn)狀和發(fā)展趨勢(shì)進(jìn)行闡述，指出木文研究的內(nèi)容和目的。其次，木
